Q. faginea and Q. pyrenaica were studied for the first time. Based on visible injury, gas exchange, chlorophyll content and biomass responses, Q. pyrenaica was the most sensitive species, and Q. ilex was the most tolerant, followed by Q. faginea. Functional leaf traits of the species were related to differences in sensitivity, while accumulated ozone flux via stomata (POD1.6) partly contributed to the observed differences. For risk assessment of Mediterranean vegetation, the diversity of responses detected in this study should be taken into account, applying appropriate critical levels.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Elsevier Ltd&lt;br/&gt;accession-num: 20974507</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Jakucs, Erzsébet</style></author><author><style face="normal" font="default" size="100%">Eros-Honti, Zsolt</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Morphological-anatomical characterization and identification of Tomentella ectomycorrhizas.</style></title><secondary-title><style face="normal" font="default" size="100%">Mycorrhiza</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Anatomy</style></keyword><keyword><style  face="normal" font="default" size="100%">ECM</style></keyword><keyword><style  face="normal" font="default" size="100%">ectomycorrhiza</style></keyword><keyword><style  face="normal" font="default" size="100%">identification</style></keyword><keyword><style  face="normal" font="default" size="100%">morphology</style></keyword><keyword><style  face="normal" font="default" size="100%">Tomentella</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2008</style></year></dates><volume><style face="normal" font="default" size="100%">18</style></volume><pages><style face="normal" font="default" size="100%">277-285</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Over the last two decades, much information has been gathered on the ectomycorrhizal fungus community composition of plant associations of boreal, temperate, and tropical regions. Worldwide, Tomentella ectomycorrhizas (ECM) are often common and dominant in the mycorrhizosphere of coniferous and deciduous forests. They are present under different environmental conditions and associate with diverse plant hosts. Tomentella sporocarps, however, are rarely found aboveground, so Tomentella species are often missing from fungus community studies based on fruit-body presence. Tomentella is a resupinate genus of Thelephoraceae (Basidiomycota) forming black-brown, brown, yellow, or ochre ECM on the roots of gymnosperm and angiosperm trees, distinguished by typical morphological-anatomical characteristics (clamped hyphae, angular mantle, surface network, special rhizomorphs and cystidia). In this paper, we review the taxonomic position and morphological-anatomical characteristics of Tomentella ECM. A short summary of the microscopic features used for distinguishing tomentelloids during morphotyping and identification is presented in order to support molecular and ecological studies of ectomycorrhizal fungus communities.</style></abstract><accession-num><style face="normal" font="default" size="100%">18622633</style></accession-num></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>3</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Leal, Sofia</style></author><author><style face="normal" font="default" size="100%">González-Pérez, Aranzazu</style></author><author><style face="normal" font="default" size="100%">Vasquez-Piqué, Javier</style></author><author><style face="normal" font="default" size="100%">Spiecker, Heinrich</style></author><author><style face="normal" font="default" size="100%">Pereira, Helena</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">VÁZQUEZ-PIQUÉ, JAVIER</style></author><author><style face="normal" font="default" size="100%">Pereir, Helena</style></author><author><style face="normal" font="default" size="100%">GONZÁLEZ-PÉREZ, ARANTZAZU</style></author></secondary-authors></contributors><titles><title><style face="normal" font="default" size="100%">cork oak wood a hard material to sample and to measure</style></title><secondary-title><style face="normal" font="default" size="100%">Suberwood2005: New challenges for integration of cork oak forests and products, Scientific and Technical Conference, Huelva, Spain, 20, 21 and 22 October 2005.</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Anatomy</style></keyword><keyword><style  face="normal" font="default" size="100%">growth rings</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber L.</style></keyword><keyword><style  face="normal" font="default" size="100%">sampling</style></keyword><keyword><style  face="normal" font="default" size="100%">wood growth</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2005</style></year></dates><publisher><style face="normal" font="default" size="100%">Universidad de Huelva</style></publisher><pub-location><style face="normal" font="default" size="100%">Huelva</style></pub-location><pages><style face="normal" font="default" size="100%">456</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Different studies within the Suberwood project required measurements of wood growth in cork oak trees (Quercus suber L.), including tree ring analysis, as a basis to analyse the influence on tree growth of stress effects, namely those deriving from climatic conditions (i.e. water deficit) or from the cork extraction. The research partners have experienced serious difficulties in these tasks and some examples are presented and discussed. The first difficulty regards sampling because cork oak harvesting is forbidden in Portugal and advantage has to be taken from legally authorised tree fellings. The available material therefore consists mainly in thinning material (young trees), dead or diseased trees, and trees with damaged stems due to improper cork harvesting, which are useless for such studies. In most cases the information concerning the stand management is lacking, namely regarding the time of cork extraction and of other silvicultural operations (i.e. pruning). Therefore the experimental design regarding treatments and repetitions often cannot follow the conventional statistical guidelines. The cork oak wood also has anatomical and structural features that bring considerable complexity for ring definition. The wood has a semi-ring porosity with poor growth ring definition and it is very difficult, and frequently impossible, to accurately identify growth rings and to link measurements to a certain year. Additionally cork extraction disturbs wood growth and anatomy. Different observation approaches were tested: overall microscopical observations, continuous radial measurement of vessel dimensions and density, continuous radial microdensitometric profiles, cambial wounding. The use of non-destructive samples (i.e. cores or small wood samples) adds to the uncertainty encountered. Stem discs offer a better observation but differences among different radii are often very large.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Ourcival, J M</style></author><author><style face="normal" font="default" size="100%">Joffre, R</style></author><author><style face="normal" font="default" size="100%">Rambal, S</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Exploring the relationships between reflectance and anatomical and biochemical properties in Quercus ilex leaves</style></title><secondary-title><style face="normal" font="default" size="100%">New Phytologist</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Anatomy</style></keyword><keyword><style  face="normal" font="default" size="100%">infrared spectroscopy</style></keyword><keyword><style  face="normal" font="default" size="100%">Leaf mass per area</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus ilex</style></keyword><keyword><style  face="normal" font="default" size="100%">reflectance</style></keyword><keyword><style  face="normal" font="default" size="100%">Thickness</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1999</style></year></dates><publisher><style face="normal" font="default" size="100%">Cambridge University Press</style></publisher><volume><style face="normal" font="default" size="100%">143</style></volume><pages><style face="normal" font="default" size="100%">351-364</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Leaf anatomical parameters such as leaf mass per area (LMA) and biochemical composition can be used as indicators of leaf photosynthetic capacity. The aims of this study are to evaluate the potential of reflectance spectroscopy of fresh leaves for assessing and predicting various parameters, anatomical (LMA and tissue thickness) and biochemical (nitrogen concentration). This paper describes results obtained with fresh leaves of holm oak (Quercus ilex), an evergreen oak that is widely distributed from mesic to xeric habitats in the Mediterranean. Fresh leaves (560) were collected over 3 yr at six different sites, from the top to the bottom of the canopy. The reflectance of each leaf was obtained within 1 h of sampling with an NIRSystems 6500 spectrophotometer over the range 400–2500 nm. LMA was determined for all samples; biochemical and anatomical measurements were conducted over representative subsample populations of 92 and 87 leaves, respectively. Stepwise regression calibrations and partial least squares (PLS) calibrations were developed and compared with different spectral regions and mathematical treatments. Calibration equations had high coefficients of determination (r2 ranging from 0.94 for nitrogen to 0.98 for LMA and tissue thickness). The PLS regressions gave better results than stepwise regressions for all parameters studied. Compared with regressions calculated on raw spectral data, calculations on second derivatives of spectra improved results in all cases. The use of scatter corrections also improved results. These results show that visible and near-infra red reflectance can be used for accurately predicting anatomical parameters and the nitrogen concentration of fresh holm oak leaves. The results support the suggestion that high spectral resolution imaging spectrometry can be a useful tool for assessing functional processes in forest ecosystems.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Fos, S.</style></author><author><style face="normal" font="default" size="100%">PÉREZ-RoViRA, P.</style></author><author><style face="normal" font="default" size="100%">Barreno, E.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">CRECIMIENTO RADIAL DEL CORCHO EN LOS ALCORNOCALES ESPAÑOLES: RELACIONES ENTRE ANATOMÍA Y BIOCLIMA.</style></title><secondary-title><style face="normal" font="default" size="100%">II Congreso Forestal Español</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Anatomy</style></keyword><keyword><style  face="normal" font="default" size="100%">bioc1imatology</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber</style></keyword><keyword><style  face="normal" font="default" size="100%">Radial growth</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1997</style></year><pub-dates><date><style  face="normal" font="default" size="100%">1997///</style></date></pub-dates></dates><pages><style face="normal" font="default" size="100%">177 - 182</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">A comparative study of the reproduction cork radial growth between the main cork productive areas in Spain is raised: Extremadura-Huelva, Cádiz, Girona and Castellón.

A aplicação de AIB à base da estaca melhorou a percentagem de enraizamento e a sobrevivência em relação à testemunha, na época de enraizamento de Abril. Na época de fins de Junho, já não se verificou a referida resposta positiva. Este tratamento não teve efeito no número de raízes formadas, por estaca enraizada, mas influenciou o comprimento da maior raiz, também por estaca enraizada, independentemente da época de enraizamento. A utilização de 0,1% ANA não provocou resultados diferentes da testemunha para qualquer dos parâmetros avaliados. O descasque na base da estaca aumentou a percentagem de enraizamento e a sobrevivência. Este tratamento, juntamente com a aplicação de 0,5% de AIB conduziu a percentagens de enraizamento superiores a 60%, ao fim de três meses de ensaio, na época de enraizamento de Abril. Quer a origem da estaca (topo ou base da planta) quer os tratamentos dos pés-mãe (colocação das plantas às escuras ou o escurecimento - uso de uma fita preta na base da futura estaca) não influenciaram a percentagem de enraizamento. A sobrevivência das estacas é comprometida na época de enraizamento de fins de Junho, pelo facto de entrarem em dormência. A aplicação de BAP às estacas enraizadas, em dormência, estimulou o abrolhamento de gomos axilares e não se observaram efeitos fitotóxicos. Realizaram-se cortes histológicos na base de estacas sujeitas ao tratamento de escurecimento (com ou sem aplicação de AIB na banda preta). No dia 0 observaram-se diferenças na estrutura devidas a esse tratamento especialmente ao nível da periderme e do xilema. Até ao dia 20 as diferenças estruturais das estacas submetidas ao tratamento de escurecimento foram-se acentuando com perda de coerência e aparecimento, por vezes abundante, de callus. Em geral as modificações surgiam na zona do nó e só depois na zona do entrenó. A aplicação de AIB à base da estaca antes de esta ser posta a enraizar não conduziu a diferenças tão evidentes como o tratamento de escurecimento</style></abstract></record></records></xml>
